CONCRETE PLAQUE AND METE [OD OF MAKING SAMIE.

Application filed October 24-, 1924. Serial No. 745,601.

concern:

Be it known that I, IRENE M. VASHING- won, a citizen of the UnitedStates of America, residing at Brooklyn, city of New York, county ofKings, State of .New York,

have invented certain new and useful Improvementsin Concrete Plaques andMethods of Making Same, of which the follow- My invention relates to theproduction of artistic plaques of cement mixtures which will present theeffect of a painting on plaque, and on which is marked the outlinecanvas or other given fabric having a characteristic surface, andreproduce-any given design. The best method at present known to me, forpractising my inventionis illustrated in the accompanying sheet ofdrawings in which:

Fig. -1 shows a sheet of canvas with a simple design of 'a' clover leafappearing thereon.

Fig.2 is a plan view of said sheet with bodies of cement applied tocertain portions thereof in the process of forming the plaque,

and

Fig. 3 is a cross section on line 3- 3 of Throughout the drawings likereference characters indicate like parts. 1 'is a sheet of canvas,burlap, or other material having a characteristic surface, arepresentation of which is to be reproduced-in the cement of the desireddesign, here shown as. a clover leaf 2. The sheet bearing the design issupported onaqy suitable plane surface 3, and a frame 4: o the desiredsize and shape is placed on the sheet 1. 6, 6, represent masses ofhydraulic cement mixed with a green pigment laced on the sheet 1 overthe sections of t e design which are colored green, and 7,a mass of suchcement mixed with a yellow pigment which extends over those portions ofthe design colored yellow. A 8 represents 'a thicker backing formed ofconcrete containing a out three parts. of sharp sand intimately mixedwith ydraulic-cement. 9 is a board on which the foregoing parts areassembled.

In operating according to my invention to make a cement plaque whichshallrepr'oducetheappearance or effect of a painting of said clover leafor other design on canvas I mix pigments correspondin to the colors tobe reproduced with suita le masses of hydraulic cement, preferably neat,moisten referably the vmasses with the proper proportion of water tocombine with said cement when setting, and place the colored masses soproduced 011 the canvas over the portions ofthe design which are to havethe same color in a layer of suflicient thickness to' form ance of apainting on canvas of the original design, being a replica of the canvassurface in the selectedcolors.

Preferably the original layer of colored before the concretebacking isadded. This is done to make sure that none of the concrete displacesthelower layer of colored cement so as to appear on the face of theplaque. Preferably also pigments are used of mineral or other characterwhich will not be soluble in the cement or affected by any of itsconstituents; This is to preserve sharpness of outline inthe design onthe completed plaque. s

While I have mentioned the use of hydraulic cement, obviously othercements might be used if plaques of fireproof or other qualitiescharacteristic of different varities'of cement are desired.

If it is desired to reproduce in the pla no the surface effect of anyother materlal, such as "cartridge paper, for instance, the originaldesign is-outlined on a sheet of that material and the cement appliedthereto as above described. 7 p

The result is an indestructible cement plaque which may be used for wallor other decoration and will produce the effect of painting ,on canvasor anyfabric havinga characteristic texture or appearance.

Having describcdmy invention, I claim: l; The method of producing in acement plaque a reproduction of a desi n resem bling a painting on anyparticu ar fabric which method comprises outlining the decement massesis allowed to partially set which a backing ofmoist concrete is added tothe layer of colored cement and allowed to set thereon."

3. A method such as set out in claim 1 in which the cement is colored bymixing therewith, while dry, pigments which are insoluble in any of theconstituents of said cement when wet.

4. As a new article of manufacture, a cement plaque having a surfacecolored to reproduce a particular design and reproducing the appearanceof texture of a particular fabric. i

5. As a new article of manufacture, .a cement plaque reproducing theeffect of a painting on canvas having a surface representing a replicaof a sheet of canvas composed of areas of cement mixed with dif-v ferentcolored pigments.

6. As a new article of manufacture, a plaque having a surface ofhydraulic cement and a. backing of concrete, said surface presenting areplica of a;given fabric and containing mineral pigments mixed with thecement to reproduce a given design in colors,

whereby the effect of a painting of said design on said fabric isproduced. 7

7. The method of producing in a cement plaque a reproduction of a designresembling a. painting on any particular fabric which methodcomprisesoutlining the design on a sheet of such fabric, applying massesof moist hydraulic cement colored to correspond to different portions ofsaid design on the corresponding areas of said fabric in a layer ofproper thickness, allowing the cement to set and finally stripping offsaid fabric from the face of the plaque so formed.

8. Themethod of'producing in a cement plaque a reproduction of a design.resembling a painting on any particular fabric which method comprisesoutlining the design on a sheet of such fabric, applying masses of moisthydraulic cement colored to correspond to different portions of saiddesign on the corresponding areas of said fabric in a layer-of properthickness, adding a backing layer of concrete containing hydrauliccement, allowing the cement-.to set and finally stripping off saidfabric from the face of the plaque so formed.
